Definitions

  • the invention relates to the manufacture of containers by blow molding or stretch blow molding, from plastic blanks such as PET (polyethylene terephthalate).
  • the blowing technique of a container comprises, firstly, a heating operation of a blank (whether it is a preform or an intermediate container having undergone a first blowing operation from a preform) at a predetermined temperature, greater than the glass transition temperature of the constituent material of the blank.
  • the blank thus heated is introduced into a mold having a wall delimiting a cavity in the impression of the container, and a blow molding operation of the blank is carried out by injecting a fluid therein (generally from air) under pressure (this pressure generally being between 20 and 40 bars).
  • a drawing operation may be provided, consisting, during blowing, of stretching the blank by means of a sliding rod ensuring the holding of the container in the axis of the mold.
  • thermofixation heat set in English
  • a first technique is to circulate in the wall of the mold a fluid (including water or oil) previously heated. This proven technique is widespread. However, it has a number of disadvantages. First, given the significant heat exchange taking place between the mold wall and the containers, it requires a flow (and therefore a reserve) of significant fluid. Secondly, the circulation of the fluid in the mold requires the drilling of complex channels in the wall of the mold.
  • a second technique consists in heating the mold by means of an electrical resistance, the heat supplied to the mold being dissipated by the Joule effect.
  • European patent EP 1 753 597 or document WO2011 / 091780 a mold support to which is attached, at an interface with a mold to the imprint of the container, a coil electrical resistance, provided with cross sections located near the ends of the mold.
  • JPS5789929 describes a method of heating a preform.
  • a first objective is to improve the energy efficiency of the electric heater of a mold.
  • a second objective is to simplify the manufacture of a mold equipped with an electric heating system.
  • a third objective is to allow a better regulation of the temperature of the mold.
  • a mold according to claim 1 which incorporates the heating system, particularly offers an energy efficiency higher than known electric heating molds. It also makes it possible to heat the container in superimposed zones, to the benefit of the heating accuracy and, ultimately, the quality (and performance) of the container.
  • a container forming unit from plastic preforms which comprises at least one such mold, or a plurality of such molds mounted on a common carousel.
  • a mold 1 for forming containers from blanks (it is usually preforms) of plastic is shown.
  • This mold 1 is intended to be integrated in a container forming unit, which comprises, for example, a carousel at the periphery of which several molds 1 are mounted.
  • This mold 1 is of the wallet type and comprises two half-molds 2 (also called shells) removably attached in two respective shell holders (not shown), mounted articulated in rotation relative to each other around a common hinge.
  • the figure 3 shows a single shell 2, shown in exploded form.
  • Each shell 2 is made integrally in a metallic material such as a steel or an aluminum alloy.
  • a metallic material such as a steel or an aluminum alloy.
  • the shell 2 is hollow formed from a flat face 3 forming a interface between the shells 2, a cavity 4 to the imprint of a final container to be formed, which extends around a central axis X of symmetry.
  • the containers to be formed are of the HR type, that is to say that they have good mechanical resistance to deformation during hot filling. This resistance is conferred on each container by an increase in its crystallinity level by thermal means, this process called thermofixation being made possible by a regulation of the temperature of the mold 1 at a high temperature (greater than 100 ° C., and preferably included between 130 ° C and 160 ° C).
  • the final container has panels for absorbing the deformations during filling. These panels are for example formed by a series of inserts 5 mounted in the cavity 4 removably, in housings provided for this purpose.
  • thermofixation consists in maintaining, at the end of its forming, the plated container against the wall of the cavity 4 for a predetermined duration.
  • the mold 1 comprises a system 6 for electric heating of each shell 2.
  • This heating system 6 comprises, for each shell 2, at least one set 7 of resistive or resistor elements 8.i (where i is an integer between 1 and N, N being an integer strictly greater than 1, N being equal to to 3 in the illustrated embodiment) distinct, superimposed substantially parallel to the central X axis and similar topology, located opposite corresponding 9.i corresponding, adjacent and superimposed areas of the cavity 4.
  • the topology of two elements is so-called when they have the same geometric properties.
  • two cylinders of revolution are known of similar topology, as well as two tori of revolution.
  • a cylinder of revolution and a torus of revolution present dissimilar topologies.
  • the heating system 6 is arranged to dissipate by Joule effect a different thermal energy at each resistor 8.i of the same set 7, to heat and temperature control adjacent areas 9.i superimposed at different temperatures.
  • Each resistor 8.i comprises an electrical conductor in the form of a helical winding (or solenoid) around a guide curve C, embedded in a dielectric insulator made of a refractory material providing good thermal conductivity while having a high electrical resistance .
  • the conductor may be made of an alloy of nickel and chromium.
  • each resistor 8.i is straight, that is to say that the guide curve C of the resistor 8.i is a line segment, the resistor being therefore, on a large scale (ie to say at the scale of the mold), cylindrical of revolution.
  • the guide curve C is an arc of circle, each resistor 8.i being therefore toric on a large scale.
  • each resistor 8.i is cylindrical, i.e., the guide curve C of the conductor is a straight line segment.
  • each set 7 constitutes in this configuration a unitary radiating element in the form of a cylindrical pencil each comprising several (three in this case) resistors 8.i coaxial which can be mounted on the same circuit electric, in series or in parallel as illustrated respectively on the Figures 6 and 7 , or independently on separate electrical circuits, as illustrated on the figure 9 .
  • Each rod 7 is mounted in a complementary cylindrical hole 10 formed in the shell 2 over substantially the entire height thereof, parallel to the central axis X of the cavity 4.
  • the rods 7, in this case four in number are distributed circularly in a regular manner at the periphery of the shell 2, at a distance substantially equal to the central axis X.
  • the hole 10 has a diameter slightly greater than the external diameter of the pencil 7, the clearance between them being, however, sufficiently low (depending on what the manufacturing tolerances allow) to maximize the contact between the pencil 7 and the shell 2 and thus limit thermal leaks and improve the energy efficiency of the mold 1.
  • the resistors 8.i within a same rod 7 extend over respective heights Hi which may be different and each correspond to a particular zone 9i of heating the cavity 4.
  • each resistor 8.i has a different intrinsic electrical resistance: R 1 ⁇ R 2 ⁇ R 3 with, preferably: R 1 ⁇ R 3
  • each rod 7 comprises a single electrical conductor having a plurality of successive abutting sections having different intrinsic strengths per arc length unit of the guide curve (rectilinear in this case) and each forming a resistor 8.I distinct.
  • the electrical power dissipated by Joule effect and per unit length by two adjacent conductors varies from one conductor to another (that is to say, a resistor 8.i to another). It follows that the heating temperature is different for each zone 9.i of the cavity 4.
  • each rod 7 can be made, assuming that the spiral winding is made of a single material, by variation of the density of the winding of the conductors (that is to say by variation of the developed length of the conductor per unit length of the guide curve C), or by variation of the section of the conductor.
  • the resistors 8.1 of the same rod 7 can be connected in series (as illustrated in the schematic diagram of the figure 6 ) or in parallel (as illustrated in the schematic diagram of the figure 7 ) on the same electrical circuit comprising a lead wire 11 and a return conductor wire 12 .
  • the son 11, 12 are preferably connected to an electrical terminal which can be integrated into a terminal block (not shown).
  • the resistors 8.1 may be independent (as illustrated in the block diagram of the figure 9 ) and integrated with independent electrical circuits. In this case, their intrinsic electrical resistances R i may be identical, the power variation from one resistor to the other resulting from a variation in the intensity of the current or the voltage that supplies them.
  • the (or each) electrical circuit is supplied with current by a generator 13.
  • the electrical circuit is connected to a control unit 14 with the interposition of a dimmer 15 controlled by phase angle or, preferably, by wave train .
  • the dimmer comprises a switch alternately ensuring the passage and the breaking of the current from the sector for predetermined respective durations.
  • the control unit 14 is programmed to adjust the ratio of the passage and cut-off times.
  • control unit 14 controls and regulates the power (via the dimmer 15 ) by feedback, as a function, for example, of a temperature parameter, such as the temperature at the right of the controller.
  • a temperature parameter such as the temperature at the right of the controller.
  • one of the zones 9.i of the cavity 4 measured by means of at least one thermal sensor 16 such as a thermocouple or a probe (for a single temperature measurement) or a thermal camera (for a thermal mapping) connected to the control unit 16 - and more precisely to the dimmer 15.
  • the system 6 operates in a one-to-one manner, that is to say that at a current of intensity I 0 (respectively at a voltage V 0 ) given there corresponds a single triplet of temperatures T1, T2, T3 in the superimposed areas 9.i of the cavity 4, and vice versa.
  • the probe 16 can be mounted in the shell 2 at any of the zones (for example the upper zone 9.1 ).
  • a thermal camera can be mounted at the outlet of the mold 1, facing the cavity 4 open.
  • the temperature T1 of the upper heating zone 9.1 is regulated to a value of between 100 ° C. and 160 ° C., in particular at about 130 ° C.
